About Us

Since 1969 we have been producing Zinc Oxide of best quality.Our standard assortment contains three varieties of Zinc Oxide, but as a family-owned company, we can offer a highly personalised service tailored to meet your individual requirements.Our product stands out of competitive brands because of its higher level of flowability. This ease of flow prevents blockage of in-plant transportation pipes.It is our utmost concern that the production is most environmentally sustainable, and we are always aiming at 100% security of supply, including reliability and the adherence of delivery dates.In order to maintain the striking quality of our Zinc Oxide we are ISO 9001 and ISO 14001-certified, and REACH registered.
